Title: Method and apparatus for stimulating heavy oil production
Inventor: NENNIGER EMIL
IPC: E21B43/34
Filed: 2001-06-21
Granted: 2008-07-29
Abstract: This invention relates to a process for the recovery of hydrocarbons from a hydrocarbon bearing formation having an extraction chamber where the extraction chamber has an extraction surface. The process has the steps of heating a solvent, such as propane, and then placing the solvent into the extraction chamber at a temperature and a pressure sufficient for the solvent to be in a vapour state in said chamber and to condense on said extraction surface. The next step is to produce a liquid blend of solvent and heavy oil and then to separate the solvent from said heavy oil. Then the solvent is purified, before being re-injected into the formation again. The purification step removes less condensable fractions from the solvent to ensure a purity that is high enough to support continued heat transfer at extraction conditions. The pressure and temperature are set to levels to cause less volatile fractions to drain away with the liquid bitumen and solvent blend that is produced, thus mitigating heat transfer poisoning.

Title: Placement guide for ablation devices
Inventor: MIKUS PAUL W
IPC: A61B17/34
Filed: 2000-03-08
Granted: 2010-05-25
Abstract: A placement guide for positioning ablation devices within a human body is disclosed. The placement guide comprises an outer catheter (10), and an inner tubular member (15) disposed within a lumen of the outer catheter. When a stop (30) on the inner tubular member engages a seat (35) on the outer catheter, a distal projection (40) of the inner tubular member extends from the distal end of the outer catheter. While monitoring the position of the inner tubular member through an endoscope inserted in its lumen, a clinician positions the distal projection within a human body for optimal ablation. After securing the outer catheter in position, the inner tubular member is withdrawn, and replaced with an ablation device (55) which is inserted distally within the outer catheter lumen until a stop on the ablation device engages the seat on the outer catheter wherein a distal projection (60) of the ablation device extends from the distal end of the outer catheter. Because the distal projection of the inner tubular member has a length substantially identical to that of the inner tubular member, the ablation device may be positioned for optimal ablation.
